2.2.1. Linear Advection Diffusion¶
Problem statement: Develope a solver for following Linear Advection Diffusion Equation.
\[\frac{\partial U}{\partial t}+c \nabla U = \nu \nabla^2 U\]
2.2.2. Non Linear Advection Diffusion¶
Problem statement: Develope a solver for following Non Linear Advection Diffusion Equation.
\[\frac{\partial U}{\partial t}+U \bullet \nabla U = \nu \nabla^2 U\]
